An object of the present invention is to provide an electrode for an electrochemical device, which is excellent in peel strength and can ensure a high degree of safety of the electrochemical device. The electrode for electrochemical device of the present invention comprises a current collector, and an electrode mixture layer on the current collector, wherein the electrode mixture layer comprises an electrode active material, a binder, and a foaming agent. And the binder is a polymer containing a diene monomer unit and/or a nitrile group-containing monomer unit, and the proportion of the diene monomer unit in the polymer and the nitrile group. containing the total proportion of the monomer units, 10 to 80 wt%, the volume resistivity R a at 25 ° C. of the laminate of the current collector and the electrode mixture layer, 0.1～200Omu · cm, and the ratio of the volume resistivity R B of the laminate at 350° C. to the volume resistivity R A of the laminate at 25° C. is 10 or more. |
